Description
Technical field
The utility model belongs to a kind of transmission accessory field, is specifically related to a kind of bearing.
Background technique
Traditional bearing generally all includes the dust cover of outer ring, inner ring, ball bearing mechanism and 2 plastic materials.And the material of dust cover is all generally plastics, described outer ring and inner ring are all provided with draw-in groove, when assembling, the two ends of dust cover by natural compression respectively with these 2 draw-in groove clampings, but when assembling, dust cover insufficient strength, easy fracture, thus the scrappage that improve product.
Model utility content
(1) technical problem that will solve
The technical problems to be solved in the utility model to prevent dust cover fracture when assembling.
(2) technological scheme
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of bearing, comprises outer ring, inner ring, ball bearing mechanism and 2 dust covers; Described inner ring, ball bearing mechanism and outer ring are placed successively from inside to outside, described inner ring and outer ring are coordinated by ball bearing mechanism and are in transmission connection, the periphery of described inner ring and the inner headed face of outer ring are provided with a draw-in groove, described dust cover includes the skeleton of metal material, the outer side surface of described skeleton is provided with the rubber card of a molding and forming, and the two ends of described rubber card are respectively arranged with the first joint end and the second joint end; Described first joint end and the second joint end respectively with the draw-in groove of inner ring periphery and the draw-in groove clamping of outer ring inner headed face.
Further, the periphery of described skeleton is provided with a flange, and described rubber card is arranged on the outside of flange.
Further, the draw-in groove of described outer ring inner headed face includes a groove towards outer ring periphery indent, and described two joint ends are connected in groove.
Further, described groove includes an inclined-plane and the plane parallel with outer ring axial vane surface; An acute angle is formed between described inclined-plane and plane.
Further, the material of described skeleton is stainless steel belt.
Further, the material of described rubber card is nitrile rubber.
(3) beneficial effect
Bearing of the present utility model, by arranging the skeleton of a metal material and being positioned at the rubber card of molding and forming on skeleton, can improve the intensity of dust cover like this, can not damage when assembling, and easy to make.

Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1-Figure 3, a kind of bearing, comprises outer ring 1, inner ring 2, ball bearing mechanism 3 and 2 dust covers 4; Described inner ring 2, ball bearing mechanism 3 and outer ring 1 are placed successively from inside to outside, described inner ring 2 and outer ring 1 are coordinated by ball bearing mechanism 3 and are in transmission connection, the periphery of described inner ring 2 and the inner headed face of outer ring 1 are provided with a draw-in groove 5, described dust cover 4 includes the skeleton 6 of stainless steel belt material, the outer side surface of described skeleton 6 is provided with the rubber card 7 of a molding and forming, by directly molding and forming on skeleton 6, so make very convenient, and connect very firm.The material of described rubber card 7 is nitrile rubber.The two ends of described rubber card 7 are respectively arranged with the first joint end 8 and the second joint end 9; Described first joint end 8 and the second joint end 9 respectively with the draw-in groove 5 of inner ring 2 periphery and draw-in groove 5 clamping of outer ring 1 inner headed face.Because the material of skeleton 6 is stainless steel, intensity is good, and adopts rubber card 7 and draw-in groove clamping, so skeleton 6 can not rupture when assembling, reduces the scrappage of product.
The periphery of described skeleton 6 is provided with a flange 10, described rubber card 7 is arranged on the outside of flange 10, it is more firm that this structure can make the second joint end 9 be connected with draw-in groove 5, and avoid traditional dust cover when assembling and the problem that easily ruptures of its joint end.
The draw-in groove 5 of described outer ring 1 inner headed face includes a groove 11 towards outer ring 1 periphery indent, and described two joint ends 9 are connected in groove 11.Described groove 11 includes an inclined-plane 12 and the plane 13 parallel with outer ring 1 axial vane surface; Form an acute angle between described inclined-plane 12 and plane 13, this connection makes dust cover 4 be connected more firm with draw-in groove 5.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
